Product Details

This MagnaFlow Rumble Muffler gives you the muffler itself, ready to be installed on your exhaust system. It measures 13 inches long, 4.25 inches tall, and 9.5 inches wide, with 2.5-inch diameter inlet and outlet ports that are on the same side (O/O configuration). This muffler is designed to give your vehicle a more aggressive, deeper exhaust note compared to stock mufflers.

The Rumble Muffler uses a straight-through, perforated core design. This design allows exhaust gases to flow with less restriction, which helps create that signature MagnaFlow sound. It's a well-built unit that's made to handle the heat and pressure of exhaust systems. While it's designed to fit a variety of applications, you'll want to confirm the inlet and outlet sizes match your existing exhaust piping or the custom setup you're building.

If you're looking to change the sound of your exhaust and want a noticeable rumble, this MagnaFlow muffler is a solid option. It's a popular choice for those who want to hear their engine a bit more without going overboard on noise.
